3 Claims.

The present invention pertains to a novel window construction of thesliding sash type wherein the sashes are also hinged on vertical axes.The principal object of the invention is to permit easy cleaning of bothsides of the sashes from the interior of the building by the simpleexpedient of swinging them on their hinges.

Another object of the invention is to provide a weather stripconstruction at the free vertical edges of the sashes for the furtherpurpose of looking the sashes against swinging movement. Obviously, ameans is provided for releasing the strips from the sashes when thelatter are to be swung. Still another object of the invention is toprovide means for automatically locking the sashes against the slidingmovement when they are swung open.

In the accomplishment of these objects, the sashes are counterbalancedagainst each other at both vertical edges. At the hinged edge of eachsash the counterbalancing system includes a locking member which isnormally disengaged from the window frame to permit sliding of thesashes. This locking member is so constructed, however, that: itautomatically interlocks with the window frame when the sash is swungoutward, with the result that the sash cannot then be further adjustedvertically. The locking member automatically disengages the frame memberwhen the sash is closed on its hinge.

At the free or swinging edges of the sashes, the frame member carriesvertically hinged weather-strips that interlock with the respectivelyadjacent sashes to hold them from swinging outward. A linkage is'provided for withdrawing the weather-strips from the sashes when thelatter are to be swung on their hinges. At this side also the sashes arecounterbalanced against each other, and a locking means fixes thecounterbalancing system to the frame member when the weather strips arewithdrawn. This locking means includes a sliding finger adapted to lockeach end of the counterbalanced chain to the frame member.

At an exposed portion on the indoor sideof the window frame if anadjustable member for operating the linkage which withdraws the weatherstrips from their respective sashes. There is an individual adjustingmember and linkage for each weather-strip. Each such linkage isconnected to the corresponding sliding finger for locking thecounterbalance system at this side of the frame. Thus, when the weatherstrips are withdrawn from the sashes, the counterbalance system'is' atthis time locked to the frame member,

with the result that the sashes are locked against vertical movement atthis side of the frame, as well as at the other side, when the sashesare swung open on their hinges.

The invention is fully disclosed by way of example in the followingdescription and in the accompanying drawings in which:

Reference to these views will now be made by use of like characterswhich are employed to designate corresponding parts throughout.

In Figure 1 is shown a pair of window frame sides I and 2 foraccommodating sliding sashes. The inner surfaces of the members I and 2are formed with specially shaped ways I and 2 in which are slidablymounted a pair of sashes 3 and 4 in adjacent vertical planes.

The frame! is formed with a pair of vertical slots 5 at the windowopening, and in each slot is slidably mounted a pair of hinge plates inthe form of blocks 6 and l as shown in Figures 5 and 14 respectively.The blocks carry complementary hinge plates 8, 8 attached byconventional knuckle hinges 9, and two such plates are fastened to eachof the sashes 3 and 4. Vertical strips H] are attached to the innersurface of the frame I and extend into the blocks 6, 1 to permit slidingthereof in the slots. The hinge plates 8 are lowermost, and each suchplate carries a lug ll adapted to enter a notch l2 in the adjacent stripH], when the sash is swung= The sashes are counterbalanced against eachother in both frame sides I and 2, and for this purpose each side framemember is provided with a pair of vertical channels l3 for receiving theconnecting chains 54. There is one such Chain in each side member,formed in twolaps by passing over pulleys l4 well known in the art.

In the member I, the ends of the chain I4 are attached to slides l5mounted in the respective channels l3. Each slide [5 is formed with asubstantial opening is in which is pivotally mounted a rocker arm I!having a hook or finger l8 at its" lower end engageable in anaperture-Tun the channel I3.

'15 The adjacent edges of the sashes carry brackets 19, each of whichisformed with.

an angular recess shaped to receivethe-inner edge of the adjacent rockerarm 11, as shown in Figure 2. By this means the sashes are suspendedfromthe chain M in theside memberi.

In the oppositeframe member 2, theends of the.

chain I4 are attachedto slidingblocks 2i mounted in the correspondingchannelsJ-iasshown in Fig-.

The operation of this devicewill subsequently be described. 1

The sashes 3 and 4 ares-normally,lockedagainst 1 swinging .by meansofangulanweather-strips25 pivotally mounted in the frame-2 and engaged innotches 26 formed in the free vertical edges of the v sashes, as shownin Figures 1 and 7. The pivotal mounting is obtained by means of square.shaf-ts 2! journalled vertically in the member 2- and hav.

A pair of sleeves 35 extend from the plate 3! into the member 2 aboveand below the bushings 32. In each sleeve 36 is slidably mounted a'shaft3'! having: a finger 38 extending from one end through. a slot 39 in thesleeve and .into notches 4H and Mlin the corresponding channel l3 andslide 2|; which projects a finger 42 entering a notch 43 in thecorresponding shaftS'l. -.Thecollar i4! is preferably loosely mounted onanother collar 44 which .in turn is fastened to the corresponding rod30; Thus, when a nipple 33 is displaced inwardly in thelmannerdescribed, the corresponding finger. 42 moves with it andslides theshaft Ea'chrod 30carries a collar'4l from 3llto move itsfinger38 out ofengagement with the corresponding block 2l andchannel 13. The

blocks 2! are thus unlocked fromtheir channels [3 by withdrawal of thefingers 38 to permit nor-1 mal sliding of the sashes However, when thesashes'areto be swung; it is preferred that they do .notslide, and :atsuchftime ;the.:fingers;.38 rare shown in Figure 3.

When the nipples 33 are moved outward, the bottom 33' of each bearsagainst the corresponding head 34. In the opposite direction, the bottom33 bears against the adjacent collar 44.

The sashes 3 and 4 are preferably locked also at the frame member lagainst sliding when they are swung on their hinges. For this purposethe finger H3 at the lower end of each rocker l1 enters theaperture l8in the adjacent channel 13 when the sash and its plate [9 are swung awayfrom therocker arm. The latter is so weighted that it assumes thelocking position at this time, as When each sash is swung to closedposition, its plate [9 restores the rocker arm I! to the releaseposition shown in Figure 2, and connects the sash with thecounterbalance chain-l4.- 'Finger [8 is double at E8" if it is founddesirable to hook plate I9 at 45.
